4-Formylaminooxyvinylglycine (FVG) is an herbicidal and antibacterial nonproteinogenic amino acid produced by several strains of thePseudomonas fluorescensspecies complex. It contains a unique vinyl alkoxyamine moiety with an O–N bond, and its biosynthetic origin remains unknown. Here, we show that thegvgcluster fromP. fluorescensWH6 is responsible for the biosynthesis of FVG and two additional O–N bond-containing oxyvinylglycines, guanidinooxyvinylglycine and aminooxyvinylglycine. Feeding studies in the producing bacteria indicate that these compounds originate from homoserine. We identify a formyltransferasegvgIthat is required for the production of FVG and characterize the activity of this enzymein vitrotoward amino acids with a side chain amine. Sequence similarity network analysis reveals that GvgI and homologues make up a distinct group from the main classes of formyltransferases.
